The general structure of the present apparatus may be that of theheel-attaching machine disclosed in Letters Patent of the United StatesNo. 1,867,560, Benjamin, July 19, 1932. As appears in Figs. 1 and 2 ofthe drawings, a bracket projecting from the front of a frame-column 22has mounted upon it a shoe-supporting jack 24, in vertical passages inwhich nail-inserting drivers 26 are movable. These drivers arereciprocated to insert in the work nails which they carry upon theirupper extremities, by connection to a horizontal crank-shaft 28journaled in the lower portion of the column. Power is supplied to theshaft 28 through a motor-driven flywheel 30 and a single-rotation clutchmechanism 32 controlled through a treadle 3%. To hold a heel upon theheel-seat of a jacked shoe for the insertion of the attaching nails, apre..- sure-head 36 is mounted to slide in vertical ways at the front ofthe column. This head is held normally raised by a tension-spring 38,acting upon a lever 49 fulcrumed within the upper portion of the columnand pivotally connected to thehead. The head is lowered to applypressure to the work by a link 32 joined to the treaclle between itsforward and rear extremities. After contact of the head with the heelhas been established and sufiicient pressure has been applied by theoperator to overcome the force of a spring 44 acting to hold the rear ofthe treadle yieldably depressed, this end rises and, through a rod 46,trips the clutch 32 to produce a single rotation of the shaft 28 with aresulting nailinserting reciprocation of the drivers 26.

The heel-attaching nails are supplied from a distributor D (Figs. 1 and19), which may be similar to that made the subject of Letters Patent ofthe United States No. 1,947,770, MacKenzie,

VII-VII section February 20, 1934, modified in some particulars tobetter enter into the present invention. It will later be described ingreater detail. The nails are delivered in successive loads from thedistributor through flexible tubes 5% and footplate mechanism F to novelloading mechanism L, by which they are transferred to the jack 24. As inthe previously mentioned Benjamin patent, the mechanism L has a slide 52guided for horizontal reciprocation in a bracket 53 projecting from thecolumn 22, the slide carrying at its forward extremity anail-transferring or loading device l. The movement of the device,tocarry it from the nail-receiving position beneath the foot-plate F toits delivering position above the jack 2%, may be produced by a rack 54upon the slide, and a gear 58 meshing therewith and turned by a shaft 51which it surrounds through a friction device 58 (Fig. i). A clutch 59may connect the shaft successively to first one and then the other oftwo bevel-gears $0, 60, which are constantly rotated in oppositedirections. One of these gears receives its motion through worm-gearing$2, a horizontal shaft E i, wormgearing tti (Fig. l), a vertical shaft38, wormgearing $53, a horizontal shaft 10 and spur-gearing ll,including an element carried by the flywheel tt. The rotation of thegear 69, thus produced, is transmitted to the companion-gear through anintermediate bevel-pinion 12. The clutch 55B is engaged to cause thenail-delivering movement of the loading device through a handlever 'l lactuated by the operator, and is shifted under the control of a cam 16on the shaft 51 to efiect reverse movement of the loading device. At theend of the travel in both directions the friction device -58 slips.

Considering now the foot-plate mechanism F and referring particularly toFigs. 3 and 5 to 11 of the drawings, its purpose is to provide terminalsfor the tubes 58 receiving nails from the distributor D, which terminalsmay be arranged quickly and by simple manipulation for allsimultaneously, to give any one of an entire set of designs inaccordance with which the nails are to be inserted. There is an annularcasing attached by opposite lugs 2'2, 92 to the interior of the column22 at the rear of an opening in the front wall (Fig. 3). For the casinga cover-plate 9 is provided, this being held in place by screws 95. Inthe opening at the center of the annulus are mounted five short tubes ornipples to receive the lower ends of the five distributor-tubes 50. Ofthese nipples, that designated as 1% is carried by a bracket W2extending from the upper face of the cover as over the casing-opening.The nipple Elli: is thus fixed in position, it corresponding to the rearhail of all inserting designs, the position of which is unvarying.Nipples :04, I04, which are to deliver the pair of nails succeeding therear nail toward the breast of the heel to be attached, are supportedupon a slide it guided in the casing. A slot ili'i in the slide receivesthe nipple Hit to avoid interference with the travel of the slide. Thenipples 59% are movable in a pair of slots lit, H0 in the slide it,these slots extending oppositely from each side of the center of theslide in a direction from front to rear of the machine, and areshouldered at M9 to rest on the upper surface of the slide. Collars Illsecured to the lower portions of the nipples prevent their upwarddisplacement. Nipples H2, Hz for the breast-nails are movable alongslots Il l, l M in a slide Elli, situated opposite the slide H16 andguided similarly thereto. The lower portionzofaeach of the nipples I04is'received. in'a slot? I. I 8, extendingtransversely of thecorresponding slot H0, and formed in each of. two opposite slides'I20,I20 guided in the casing in paths at right-angles to the slides I06 andH6. Movable beside each of the slides I20 is a slide N L-having a islotI26located similarly to the slot H8 and receiving the. nipples M2 forthe breast-nails. Each ofzthe six slides has a portion I23 extendinginwardly parallel to the body of the slide and provided at its inner endwith a contact-surface I30.

.TItiWill be seen that acting upon each of the movable nipples for thetubes 50 are two slots, disposed transversely to each other; that is, apainof. slots H and M8 for each of the nipples IJ04.-.and a'pair ofslots H4 and I26 for each of the-nipples I I 2. If the slides in whichthese slots are' formed are shifted in their Ways, forces will be"applied to each nipple tending to move it in directions at right-anglesto each other. These component forces will give a resultant causingthenipple to be shifted in any desired direction and through a distancedepending upon the extentof movement of the two slides. By a propercontrol of theactuating slides, any nipple may be carried to anypredetermined point within the range of movement, and thus thenail-delivering elements of i the foot-plate F arranged in accordancewith any one of a plurality of widely varying inserting designs. Iprefer to eifect this travel of the slides by a bank of cams rotatablein the casing, there being a cam for individual engagementwith each ofthe contact-surfaces I30 of the slides. Therefore, in the presentinstance, there are six of these cams. Those for the slides I06 and H6aredesignated as I40 and I42, respectively. For the slides I20, I20 arecams I 44, I44, identical in contour but differing in their angularpositions by 180, and there are similarly formed and related cams I46,I40 for the slides I24, I24. Between the cams at the center of the bankis included a worm-wheel I48 through which all the cams are turned as aunit, they being maintained in fixed relation to one another and to theworm-wheel by vertical pins I50 passing through them. Thecontact-surfaces 930 of live of the slides are held in constantyieldable engagement with the peripheries of the cams by torsion-springsIEI, each surrounding a projection I52 from the casing and bearingagainst the slides or against projections I54 therefrom. The sixth slideI06 is acted upon by a leaf-spring I55 attached to the casing.

"Rotatable in bearings I56 upon the rear of the casing 90 is a shaftI58, having fast upon it a worm I60 meshing with the worm-wheel I48. Theshaft extends to one side of the frame-column 22,where it is readilyaccessible to the operator. Here it is furnished with a bearing upon abracket I 6| attached to the column (Fig. 3). Mounted uponthe bracket isindicating mechanism I, which may-have a rotatable dial I62 bearinggraduations and the designations of the various inserting designs inaccordance with which the nipples of the foot-plate are to be set.Worm-gearing I63 connects the dial to the shaft I50. The gradua'tionsaremovable past a fixed index-point I64, asthe shaft I58 is turned by ahand-crank I 66 upon itsouter extremity. The relation between thecontours of the cams I40, I42, I44 and I46, the contact-surfaces I30 ofthe slides I06, H6, I20 and I24 and the graduations of the dial I62, issuch that when the crank I60 is turned to bring apartic'ular graduationopposite the index-point I64, the bankof. cams --will have-beenucarriedto a predetermined angular-position. Thepairs of intersectingnipple-controlling slots in the-slides will therefore have carriedeachof the'nipples to its correct positionin the chosen design. The effectmaybe seenby comparing the relation -of the elements in Fig. 5, for theformation of the largest inserting design; with that of Fig. 9, for theslmallestdes'ign.

The novel loading mechanism L, to-which the foot-platemechanismFdelivers the nails, may be best seen in Figs. 1, 3,-4 and 12 to 18 ofthe drawings. The reciprocatory loader-slide 52 has extending outwardlyfrom it near its forward extremity a bracket I10, in which is rotatableasleeve I12, while rotatable in the sleeve is a short shaft I14. Theouter end of the sleeve hasan annular flange I16, to the periphery ofwhich is attached a cylindrical casing I18 having a set of openingsNil-corresponding to a particularnailing design. These openings arethrough a plane surface I19 upon theexterior of the casing,--to conformmore closely to the delivery-ends of the foot-plate nipples, fromwhichthe openings receive fastenings, and to the top of the jack 24, to thepassages in which they deliver fastenings. fhe casing may be retained inplace separably upon the flange in a definite circumferential relation,by a spring-pressed latch IBI movable in the flange and entering. anopening in the casing. Within the casing, fast upon the shaft I14 andjust outside the sleeve-flange I16, is a circular flange I82. In thisflange is a radial pocket I84, arranged to receive from the nipple I00of the foot-plate F the rear nail for all designs and to co-operate withone of the casing-openings I80.

The shaft has a reduced axial extension I88, about which is a cylinder Iheld in place by a thumb-nut I92 threaded upon the end of the eX-tension. The angular position of the cylinder about the shaft-extensionis determined by an interengaging radial tongue-and-groove connection atI94. The cylinder is provided with a set of pockets I06 corresponding toand co-operating with the casing-openings I80, these, with theflange-pocket I 34, completing the nail-carrying means for theloadingdevice I. Relative rotation between the flange I62 and cylinder I90 andthe casing I18 about a common axis may cause the registration ornon-registration of thepockets and openings, and therefore the dischargeor retention of the nails. Upon removing the retaining nut I92, thecylinder I90 may be separated from the shaft-extension and the casingI13 withdrawn from the latch I8I, and elements having holding meansarranged for other nailing designs substituted. Or the cylinder andcasing may be provided with a plurality of corresponding sets of pocketsand openings for different designs, these being made selectivelyeffective by having a plurality of differently disposed openings for thelatch IBI and similarly arranged grooves for the connection I94.

Nails or other fastenings are supplied by the tubes50 from thedistributor D,points down, and must be delivered to the jack 24,points-up, for insertion in the work. This inversion, I accomplish byrotation of both flange-I16 with the casing I18 and the flange I 82 andcylinder I90. The sleeve I12 and shaft I14, respectively carry a pinion2G0 and a pinion 202. 'The slide 52rhas projecting fromone side near'itsrear extremity a bracket 204 (Fig. 15), and in this bracketand in thebracket I10 a sleeve 206'is rotatable. "A shaft "208 'is arrangedto turnwithin thesleeve 2662 Rotation of the sleeve 266 is communicated to theshaft I14 through a pinion 269 meshing with the pinion 202, while apinion 2H transmits the rotation of the shaft 288 to the sleeve I12through the pinion 280. Extending longitudinally of the sleeve 286 is aslot 2H) of a length substantially equal to the extent of travel of theloading device l. In the shaft 208 is a groove 2l2 of like length (Fig.1'7). At or near the center of both the slot and groove is a curvedcamportion 2 l4, extending through about 180 of the circumference ofeach and being of the same form in both. Except for the cam-portion 21d,the shaft-groove is straight throughout its length, although in twosections at opposite sides of said cam-portion. The form of thesleeve-slot coincides with that of the shaft-groove, except that at theends of the former there are oppositely inclined offsets 2I6, 2K8.Rotatable on the bracket 53 is a roll 228 lying in both the slot andgroove. As said slot and groove travel along the roll in thereciprocation of the loaderslide, the relation between the nail-holdingpockets of the flange I82 and cylinder We and the nail-dischargingopenings of the casing lid is such, that when the straight portionsengage the roll an angular relation is established in which the pocketsare closed by the imperforate portion of the casing-wall. This relationis maintained during the passage of the cam-portions 214 along the roll,although the cylinder and easing will be inverted together by thecam-portions Ri l. When, however, either offset 2E6 cooperates with theroll, the sleeve 266 only is turned. This brings the pockets of theflange I82 and cylinder 198 into registration with the casing-openingsthrough rotation of the pinion 289, pinion 282 and shaft H4.

There results the following action during each nail-transferring cycle.When the loading device l is beneath the foot-plate F, the forwardoffset 2E6 of the sleeve-slot 2lfl engaging the roll 226 shifts thesleeve 286 and therefore the flange I82 and cylinder tilt, to open thepockets lt l and I86. The openings in the casing H8 are at this timeuppermost, as appears in Fig. 12, held beneath the nipples of thefoot-plate ready for the reception of the load of nails, supplied pointsdown. When the advance of the loading device is produced as a result ofthe actuation of the lever 74, as soon as the sleeve-offset leaves theroll 228, the straight portion of the sleeve-slot coming intoregistration with that of the groove causes the pockets to leave thecasing-openings so they are closed. As the loading device continues itstravel toward the jack 2%, the camportions 2l4 of the slot and groovereach the roll and impart to the entire loading device a half turn, thestill closed pockets now being directed downwardly with the nailsretained point up. When the loading device reaches and passes above thejack, the rear offset 216 of the sleeve is acted upon by the roll andshifts the pockets sufiiciently to again bring them into registrationwith the casing-openings. These are now above the jack-passages (Fig.13), so the nails fall heads down upon the drivers 2%. During the returnof the loading device to the foot-plate, the movements of the casingIt'll, flange i82 and cylinder I98 occur in the reverse order.

The delivery of nails from the distributor D to the loading device lthrough the foot-plate F is governed in such a manner that nonailretaining shutter is required at the foot-plate, and delivery cannotbe made until the loading device has dropped its nails into the jack 24and said nails have been driven from the jack, so all the elements areready for the supply of another load. The distributor is shown as havingconventional slotted raceways 226 (Figs. 1 and 19) down which series ofnails flow, hanging by their heads. At the ends of the raceways thenails are picked off, load by load, by a delivery device in the form ofa reciprocatory slotted plate 228, the carrier 229 of which is moved tothe right idly under the power of the machine and then in the oppositedirection under the influence of an expansion-spring 238, for the plateto separate the nails and hold them to be dropped into the tubes 50.This nail-discharging movement of the plate is under the control of theperipheral portion of the cam 16 (Figs. 1 to 4) which is rotated by theshaft 51 during each nail-delivering movement of the loading mechanism.With this cam-portion contacts a roll 2332 upon one arm of abell-crank-lever 234 fulcrumed outside the column. To a second arm ofthe lever is joined a link 236, surrounding which is an expansion-spring238 interposed between a projection 248 from the column and a collar 282fast on the link. The spring urges the link down and the roll intoconstant engagement with the cam. About the upper end of the link is acompression-spring 244, supported between a collar 246 secured to thelink and one arm of a bell-crank-lever 248 fulcrumed upon the end of thedistributor below the carrier 229, through which arm said link passesloosely. A collar 249. secured to the link above the lever-armdetermines the angular position of the lever. A second arm of the lever248 has pivoted to it an upwardly extending link 258, through a slot inwhich passes a pin 252 fixed in the side of an actuating member 254 inthe form of a hook, this hook being pivoted upon an upwardly extendingarm of a bell-cranklever 256 fulcrumed with the lever 248. Atorsion-spring 258 surrounding the pivot of the hook holds said hooknormally raised, with the pin 252 in engagement with the top of theslot. But when the cam '56 acting through the lever 248 and link 258depresses the hook, it contacts with an upper inclined surface 259 of aprojection 26!! from the picker-plate-carrier, and forces this to theright against the force of the spring 238. The point of the hook is thenlatched in engagement with the projection by extending beneath anoverhang 262 of said projection. A second arm of the lever 256 isconnected by a link 26% to one arm of a lever 266 fulcrumed in the rearof the lower part of the frame-column and provided with a roll 268 (Fig.2). This roll rests against the periphery of a seconddeliverycontrolling cam 2H1 fast on the shaft 28, rotated through theclutch 32 to actuate the drivers 26. Engagement of the roll with the camis yieldably maintained by an expansion-spring 212 interposed betweenthe frame 22 and an adjustable collar 216 upon the link 264.

Initially, the loading device I contains a load of nails supplied duringthe preceding operating cycle. The hook 254 at the distributor is raisedby its spring 258 with its point above the surface 258 upon theprojection 268, as appears in Figs. 1 and 19. The operator actuates thelever '54, causing the loading device to advance and deliver its load ofnails to the jack 24 and return to its position beneath the foot-plateF. As the cam '16 rotates, it acts upon the lever 234 and through thelink 236, lever 248 and link 250 draws down'the hook. The engagement ofthe point 'of' thehook with the incline 2591of'the picker-projectionforces the picker-plate 228 to the right against the force of the spring2313. As the point of the hook passes below the end of the incline, thespring returns the picker-plate tovth'e left, latching the hook beneaththe overhan'gf262.- Thus, the picker mechanism of the distributor hasbeen prepared for the supply of a load of'nails'to the device I, therotation of the cam'- T6duI'ing the reciprocation of the loadingmechanism L showing that said device has made its'.'delivery to the jackand is therefore empty and in :position to receive another load. Theoperator now jacks a shoe, applies a heel to the heel-seat and depressesthe treadle 3d. This first brings down the head 36 to apply pressuretothe work, and then trips the clutch 32 to turnrthe shaft 28 through asingle rotation. The drivers 26*are thus reciprocated, to insert thenails-which'the device I has just delivered to them'; to attach'the heelto the shoe. The previously contained nails having been driven from the"jack, it isready for the reception of another load: With the shaft 28,the cam Z'ill rotates through.360. Byits eifect on the lever 266, itactuates the link 26!! and the lever 256 to draw the hook 254, with thepicker-plate 228, to the right The cam 270 now permits the actuatingelements -to move reversely, so the spring 230 carries the picker-plateto the left, separating aload-of-nailsfrom the raceways and droppingthem ':through the tubes 56 and the nipples of the foot-plate mechanismdirectly into the pocketsof the waiting loading device. Control of theentrance of the nails into the loading device is wholly by the properlytimed operation of the picker-plate, no foot-plate-shutter beingnecessary. The contour of the cam 210 allows the hook 254 to travelfarther to the left than does the picker-plate, and then returns it toits initialilposition above the surface 259 of the projection 260*. The.hook. has thus. been released from the projection to be raised by thespring 258, and all the elements are ready for the supply of anotherload from the distributor, when the actuation of the lever M by theoperator disposes of the nails which the loading device contains.
